CY7C65620-56LFXC - USB 2.0 Low-Power 2-Port Hub Controller | Infineon Technologies

A USB hub controller is an interface IC that manages USB traffic between one upstream USB port and multiple downstream ports. In the USB hierarchy, the CY7C65620 belongs to the interface-controller class and provides the device-side logic needed to organize downstream USB connections. Its low-power design focus helps systems that must balance USB functionality against battery and thermal budgets, while the integrated 24 MHz external crystal interface with an integrated PLL provides a defined clock source for USB operation.
Verified product information identifies the EZ-USB HX2LP family with integrated upstream and downstream termination resistors, integrated port status indicator control, and configuration through an external SPI EEPROM. The controller supports in-system EEPROM programming, including configurable vendor ID and product identification information. These features can reduce board-level component count and provide a path to field-configurable USB identity without changing the hub-controller IC.
The CY7C65620-56LFXC is targeted at USB 2.0 hub implementations where a compact 56-QFN package and low-power controller are useful. Compared with a discrete host-side hub design, an integrated controller centralizes USB protocol handling, port status management, and configuration support. Design work should still validate the controller's electrical timing, crystal requirements, termination configuration, EEPROM programming procedure, and thermal performance against the latest manufacturer datasheet before production release.
The available distributor records identify both Infineon Technologies and Rochester Electronics listings for the same MPN, while Mouser and Octopart provide additional sourcing visibility. Pricing, lead time, and lifecycle status are not consistently exposed in the supplied records, so those commercial fields require confirmation from an authorized distributor or a current XAIPART quotation.
This page combines the verified manufacturer-related and distributor data with engineering-oriented guidance on USB hub implementation, EEPROM configuration, clocking, port-status control, and supply-chain risk. It is intended to help engineers evaluate whether the CY7C65620-56LFXC is suitable for a compact USB 2.0 hub design, while clearly identifying parameters that still require datasheet or commercial confirmation.

Aplikasi Umum
CY7C65620-56LFXC cocok untuk 6 aplikasis: Compact USB 2.0 Docking Station, Embedded USB-to-Device Interface, USB 2.0 Printer Hub, Industrial USB-to-Industrial Peripherals, USB Test and Measurement Front Panel, USB Storage and Media Hub.
Compact USB 2.0 Docking Station
The CY7C65620-56LFXC fits a compact USB 2.0 docking hub where a dedicated hub controller simplifies downstream port management. Its two-port USB 2.0 positioning and 56-QFN 8 x 8 mm package help preserve board area in small docks. Integrated upstream and downstream termination resistors can reduce the number of external USB termination components, while integrated port-status indicator control supports visible port activity feedback. The controller should be paired with the required connector, power-management, and downstream overcurrent-protection implementation.

Embedded USB-to-Device Interface
The CY7C65620-56LFXC is appropriate for embedded equipment that exposes two downstream USB connections from one upstream USB interface. The 24 MHz external crystal with integrated PLL provides the stated clocking arrangement, and external SPI EEPROM configuration permits USB identity data to be programmed during production. Engineers should allocate stable clock and EEPROM routing close to the controller and validate enumeration, suspend, and downstream-port behavior in the complete device.

USB 2.0 Printer Hub
A printer or peripheral enclosure can use the CY7C65620-56LFXC to manage a compact USB 2.0 hub section around the primary printer connection. The integrated port-status indicator control is useful when the design includes activity LEDs, while the small 56-QFN footprint reduces routing congestion near board edges. The actual hub power budget, connector overcurrent behavior, and USB device-class compatibility must be verified in the system schematic because the supplied distributor records do not provide those electrical limits.

Industrial USB-to-Industrial Peripherals
The CY7C65620-56LFXC can be used in industrial equipment that needs a standardized USB 2.0 connection to multiple internal or external peripheral modules. Its low-power hub-controller positioning is useful when the product must add USB connectivity without the complexity of a full host computer. Integrated termination resistors and EEPROM-based USB identity configuration support repeatable manufacturing, but environmental ratings, ESD strategy, and isolation requirements should be selected at the system level and verified against the manufacturer documentation.

USB Test and Measurement Front Panel
Instrumentation front panels can use the CY7C65620-56LFXC to provide two USB 2.0 downstream connections for service laptops, calibration equipment, or storage accessories. The 56-QFN 8 x 8 mm package allows placement near front-panel connectors, and integrated port-status indicator control can drive activity indication without a separate indicator controller. Because test equipment may require controlled leakage current, robust ESD protection, and defined power limits, those requirements must be validated separately rather than inferred from the hub-controller family summary.

USB Storage and Media Hub
The CY7C65620-56LFXC can support a two-port USB 2.0 media or storage hub, particularly in compact adapters that combine data storage access with removable-media connectivity. External SPI EEPROM programming allows vendor and product identification to be established consistently across production units. The design must account for media-device power peaks and enumeration timing, neither of which is specified in the supplied distributor data; the controller's low-power positioning should therefore be checked against the overall hub power budget.

Catatan Desain
Calculate the hub power budget before layout. The verified records identify a low-power USB 2.0 hub controller and integrated termination resistors, but do not state downstream current limits, so downstream port budget, inrush, and suspend behavior must be confirmed from the manufacturer datasheet and the attached power-supply design. Do not assume that a controller-level low-power rating covers the complete downstream load. Use the available USB supply-distribution and protection design to prevent an attached device from overloading the rail.
Route the 24 MHz crystal connection, external SPI EEPROM, USB differential pairs, and power pins with priority. Keep USB differential routing impedance-controlled and as short as practical, with the crystal and EEPROM placed close to the controller according to the manufacturer layout guidance. Because the supplied data identifies the 56-QFN 8 x 8 mm package but does not provide the complete exposed-pad land pattern, verify thermal-pad connection and pin numbering against the official package drawing before release.
Do not substitute an orderable suffix based only on the distributor listing. The related CY7C65620 variants can differ in ordering code, temperature grade, qualification, or packaging details even when the USB 2.0 hub function and 56-QFN format are unchanged. Build a replacement checklist covering exact MPN, package drawing, pinout, clock requirements, EEPROM behavior, operating temperature, lifecycle status, and USB enumeration before approving any alternate.
Informasi Konformitas
Compliance declarations are not explicitly present in the supplied verified records. Verify RoHS, REACH, halogen-free, and conflict-minerals status using the current manufacturer product declaration.
